What countries are visa-free to Thailand?

Thailand Visa-Free Countries: Which Nations Need No Visa?

Okay, here's my take on Thailand's visa-free situation, written kinda how I'd actually talk about it. This is based on stuff I know, things I've experienced, and a touch of maybe slightly-wrong remembering!

Thailand Visa-Free (For Tourists)

Brazil, South Korea, and Peru are visa-free for tourism in Thailand.

I think it's super cool Thailand has this deal with certain countries.

Bilateral agreements (90-day visit) exist w/Brazil, South Korea, & Peru for diplomatic/official/ordinary passport holders.

It always feels a bit like a puzzle piecing together all the visa rules.

I think last time I looked it up, citizens of Brazil, Korea (South), and Peru get to skip the visa hassle for tourist visits. That's pretty sweet, right? Like, imagine just booking a flight and GOING. No paperwork nightmares.

But then, there's this whole other layer, I remember from somewhere... it's about diplomatic and official passports. I think (and I might be wrong here, so double-check!) that Thailand has special agreements with Brazil, South Korea, and Peru regarding those too.

Basically, if you have a fancy passport and you're from one of those countries, you can chill in Thailand for up to 90 days without needing a visa. Pretty neat deal if you ask me. Always double-check the exact rules official though, just to be safe you know.
